Development of Functional Guar Gum-Based Highly Water Absorbent and Investigation of Reaction Parameters

The present article describes guar-gum (GG) polysaccharide-based eco-friendly highly water absorbable polymer network with itaconic acid (IA) and acrylamide (AAm) as monomers, prepared due to characteristic features such natural abundance, biocompatibilities, biodegradability well biological physicochemical properties. solution polymerization technique was used successfully synthesize the GG-g-PIA-co-AAm co-polymer. In this method, IA AAm monomer polymerize onto polysaccharides GG in an aqueous medium at 70 °C potassium persulfate (KPS) acting a chemical initiator N, N′-methylene-bisacrylamide (N-MBA) cross-linker. maximum allowed time complete reaction 1 hour 20 minutes. consequence of neutralization degree acid, GG, AAm, N-MBA, KPS optimized. Surface morphology binding behavior were characterized by FTIR SEM microscopy. grafting (between crosslinking reactions produced solid empathy between NH2 groups guar gum carboxylic poly leading formation amide bonds. Various parameters like free-absorbency capacity (FAC) high possible (AUL) also studied for efficient absorbent polymers. A hypothetical mechanism polymeric during has been proposed.
